Inspired by the need for a SIMPLE way to measure water velocity and level in open channels, the SonTek-SL (affectionately known as the Side-Looker or "SL") has earned worldwide acceptance as a long-term monitoring solution. Now, with two new (3G) models turbo-charged by our proprietary SmartPulseHD®, the SonTek-SL features accessories, mounting options, software, and a variety of integration formats to ensure it fits your application.

Designed specifically for side mounting on bridges, canal walls, or riverbanks, the SL's SLEEK, low-profile housing makes installation easy. With three models to choose from, the SL can be used in channels as small as you can jump across to rivers as wide as the Amazon. Ultra narrow beam widths combined with unmatched side lobe suppression provide the SUPERIOR acoustic directivity necessary for achieving maximum horizontal range free of interference from surface or bottom boundaries.

Specifications

Software

First time users can collect test data within minutes of receiving the SonTek-SL. Deployments require only a few minutes to configure the SL and start collecting data. This system provides the highest quality Doppler velocity data without requiring the user to become an expert on Doppler technology.

Features

Water Velocity and Level: Water velocity, level, flow, and total volume-multiple parameters from one easy-to-use instrument. Acoustic Doppler profile of velocity data and acoustic water level offer the most accurate, reliable measurements.

SmartPulseHD®*: An intelligent algorithm that looks at water depth, profiling range, velocity, and turbulence, and then acoustically adapts to those conditions using pulse-coherent, broadband, and incoherent techniques. Best data possible under any condition. High-def cell sizes down to 4 cm.

Compact, Hydrodynamic Design: Incredibly lightweight and easy to transport and mount. Slim shape is easy to maintain, stays clean, increases available sample area, and fits into more places.

For SonTek-SL1500 (3G) and SonTek-SL3000 (3G) models only. The SonTek-SL Intelligent Flow software is an all-in-one package for interfacing with the 3G models of the SonTek-SL. Interface with the system, do setup, prepare deployment templates, run diagnostics, download data, create graphs and export data, all from the same intuitive software screen.

Become an instant velocity-indexing pro! FlowPack allows you to generate easy to interpret Velocity-Index ratings. Promising to make your data reporting process a whole lot friendlier (and faster), FlowPack also provides a simple method to store flow, velocity, and stage measurements — all through one software program. FlowPack can produce comprehensive reports that assist you in making better, more informed decisions.

Recent update corrects Modbus Output "Level" Parameter: The Modbus output of the "Level"parameter in Register 30051 & 30052 was corrected to not include the SystemElevation used in the "Stage" parameter and the flow calculations. It is now simply the water level above thevertical beam as intended. The changedoes not affect any other output formats (i.e. SDI-12) or internally recorded data.

Previous udpates include:

Adds two new Channel Types (Culvert and Equation)

Improved Total Volume calculations; allows accumulating volume even when collection is temporarily interrupted

Option added to disable Total Volume Reset on the Flow Display

Adds SDI-12 Auto Sampling, which allows instrument to continue data collection even when no data logger command is received

Scaling of analog output signals now based on setting of Total Volume units

If you wish to take advantage of the new features in this version, follow the instructions below based on the version of firmware currently in your system.

Argonaut SL/SW/XR Firmware Version 7.0 or later

This is a free update for systems that currently have v7.0 or later firmware installed. We strongly recommend updating your system to this new version. To update your system to this version:

Download and install the latest version of SonUtils - v4.20 (or later) for Windows 7/Vista/XP/2K, or v2.50a for Windows 98/95

Download and install the latest version of the ViewArgonaut Software program (v3.62 or later).

Download the Argonaut SL/SW/XR Firmware v12.0 Update Package - This package includes release notes that explain the new features and how to take advantage of them. It also includes the firmware file, your serial number access code, and instructions for loading the firmware into your system.

Argonaut SL/SW/XR Firmware Versions before v7.0

Any system with a firmware version before v7.0 would need to be returned to SonTek for a hardware upgrade. There is a fee for the hardware upgrade service. Please contact our Support team for an RMA to upgrade your systems.

Opportunities and challenges facing the largest concrete lined irrigation channel in the world

India is emerging as a world leader in irrigation schemes, and the 458-km Narmada Main Canal – the largest concrete-lined irrigation canal in the world – stands as a monument to the opportunities and challenges that face water providers. The scale of the SSNNL canal system, velocity changes due to volume and management, and the constant battle against siltation illustrate the importance for accurate measurement of flow and discharge.
